This high-activity excited reactive oxygen species is exclusively lab research grade reagent, widely applied in organic synthesis, pharmaceutical development, biochemistry & environmental analytical chemistry fields. Organic fine synthesis uses singlet oxygen for selective ene reaction, endoperoxide cyclization and heteroatom oxidation of olefin, furan, thiophene to build drug intermediate skeletons, replacing heavy-metal oxidant for green oxidation route design. Pharmacology R&D employs it to simulate intracellular oxidative damage research, study DNA guanine oxidative modification into 8-OHdG and anti-tumor photosensitizer (methylene blue, rose bengal) efficacy screening for photodynamic therapy raw material evaluation. Plant physiology labs utilize it to research chloroplast photosystem oxidative stress and plant aging mechanism simulation. Environmental testing applies standard singlet oxygen to calibrate ROS detection probes and validate wastewater organic pollutant photo-degradation efficiency simulation; prohibited for food additive, cosmetic raw material and direct human injection formulation.
GHS reactive hazardous gas with strong oxidizing property, hazard codes H270 (may cause or intensify fire; oxidizer), H315, H319, H335. All generation experiments must be operated inside fully ventilated fume hood; operators equip full-face anti-splash goggles, nitrile anti-oxidation gloves and flame-retardant lab coat to avoid direct inhalation and skin exposure to concentrated singlet oxygen vapor. Skin/eye exposure after accidental high-concentration contact needs continuous large-flow clean water flushing over 15 min with timely medical consultation for persistent irritation. High-concentration singlet oxygen triggers spontaneous combustion of grease, organic solvent, rubber and reducing chemicals; strictly separate from alcohols, ether, phosphorus powder, sulfide raw materials during experiment setup. Waste tail gas mixes with excess inert nitrogen then vented after dilute treatment per local environmental laws; no sealed compression storage for this unstable excited oxygen.
